Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Druckmesseinrichtung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass der Kraftpfad zum Messen des in der Kammer herrschenden Druckes von dem Gehäuse der Druckmesseinrichtung entkoppelt ist, so dass eine verbesserte Messung des Druckes mittels des Drucksensors ermöglicht ist.The Pressure measuring device according to the invention with the features of claim 1 has the advantage that the force path for measuring the pressure prevailing in the chamber from the housing of the Pressure measuring device is decoupled, allowing improved measurement the pressure is enabled by means of the pressure sensor.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der im Anspruch 1 angegebenen Druckmesseinrichtung möglich.By in the subclaims listed activities are advantageous developments of specified in claim 1 Pressure measuring device possible.
Der Sensorkäfig kann direkt mittels einer Verbindung, insbesondere einer Schweißverbindung, an dem Verbindungsabschnitt des Gehäuses mit dem Gehäuse verbunden sein. Ferner kann der Sensorkäfig indirekt mit dem Gehäuse verbunden sein, indem der Sensorkäfig mit dem Fixierelement verbunden ist und das Fixierelement mittels einer Verbindung, insbesondere einer Schweißverbindung, an dem Verbindungsabschnitt des Gehäuses mit dem Gehäuse verbunden ist. Dabei besteht der Vorteil, dass ein modularer Aufbau der Druckmesseinrichtung möglich ist. Insbesondere kann der Sensorkäfig mit dem Fixierelement, dem Drucksensor und gegebenenfalls weiteren mit dem Sensorkäfig verbundenen Elementen vormontiert werden, so dass bei der Montage der Druckmesseinrichtung nur noch eine Verbindung des Sensorkäfigs beziehungsweise des Fixierelements mit dem Gehäuse mittels einer Schweißnaht oder dergleichen erforderlich ist.Of the sensor cage can directly by means of a connection, in particular a welded joint, to the connecting portion of the housing with the housing be connected. Furthermore, the sensor cage can be indirectly connected to the housing be by the sensor cage is connected to the fixing element and the fixing by means of a connection, in particular a welded joint, at the connecting portion of the housing with the housing connected is. There is the advantage that a modular design the pressure measuring device possible is. In particular, the sensor cage with the fixing element, the pressure sensor and optionally further connected to the sensor cage Elements are pre-assembled, so that during assembly of the pressure measuring device only one connection of the sensor cage or the fixing element with the housing by means of a weld or the like is required.
In vorteilhafter Weise ist ein federelastisches Element vorgesehen, das innerhalb des Gehäuses angeordnet ist und das einerseits zumindest mittelbar mit dem Kraftübertragungselement und andererseits zumindest mittelbar mit dem Sensorkäfig verbunden ist. Dadurch ist keine Verbindung des federelastischen Elements mit dem Gehäuse erforderlich, so dass eine gewisse Vorspannung des federelastischen Elements vorgegeben werden kann. Insbesondere wird eine Spannungsbeaufschlagung des federelastischen Elements durch die Montagespannung, die beim Einbau der Druckmesseinrichtung in einen Zylinderkopf oder dergleichen auftritt, vermieden. Ferner werden auch während des Betriebs der Brennkraftmaschine auftretende Spannungen im Gehäuse der Druckmesseinrichtung nicht auf das federelastische Element oder andere Elemente in dem Kraftpfad zwischen dem Kraftübertragungselement und dem Drucksensor übertragen, so dass eine hohe Zuverlässigkeit der Druckmesseinrichtung gewährleistet ist.In Advantageously, a resilient element is provided, which is arranged inside the housing is and on the one hand at least indirectly with the power transmission element and on the other hand at least indirectly connected to the sensor cage is. As a result, there is no connection of the elastic element with the housing required, so that some bias of the elastic Elements can be specified. In particular, a voltage is applied of the elastic element due to the mounting tension applied during the Installation of the pressure measuring device in a cylinder head or the like occurs, avoided. Further, even during operation of the internal combustion engine occurring voltages in the housing the pressure measuring device is not on the elastic element or other elements in the force path between the power transmission element and transmitted to the pressure sensor, so that high reliability the pressure measuring device guaranteed is.
Die definierte Vorspannung des federelastischen Elements kann beispielsweise bei der Verbindung des Fixierelements mit dem Sensorkäfig vorgegeben werden. Dies hat den Vorteil, dass bereits vor der Endmontage eine definierte Vorspannung eingestellt werden kann. Ferner kann die Vorspannung bereits bei der Verbindung des Fixierelements mit dem Sensorkäfig auf den gewünschten Wert eingestellt werden, ohne dass die beim Einbau der Druckmesseinrichtung auftretenden axialen Kräfte berücksichtigt werden müssen, da diese die Vorspannung des federelastischen Elements nicht beeinflussen. Das federelastische Element kann beispielsweise als Metallmembran ausgestaltet sein.The defined bias of the resilient element, for example specified in the connection of the fixing element with the sensor cage become. This has the advantage that even before the final assembly defined bias can be adjusted. Furthermore, the Bias already in the connection of the fixing with the sensor cage the wished Value can be adjusted without affecting the installation of the pressure measuring device occurring axial forces considered Need to become, as these do not affect the bias of the resilient element. The resilient element can, for example, as a metal membrane be designed.
In vorteilhafter Weise ist ein Wärmeausdehnungskoeffizient eines Werkstoffs des Fixierelements so gewählt, dass ein Kompensieren von Dehnungsunterschieden zwischen den Bauteilen der Druckmesseinrichtung, insbesondere des Sensorkäfigs und des Drucksensors, erfolgt.In Advantageously, a coefficient of thermal expansion is a material of the fixing element chosen so that compensating of differences in expansion between the components of the pressure measuring device, in particular of the sensor cage and of the pressure sensor takes place.
